To all whomt mag concern Be .1t;known that I, :EDMUND S.'CHUROH,

-a citizen of the United States, residing at driving its type carrier being controlled by the other'of said springs.

Another object of this invention is to provide an improved setting means for the type-carriers so that they may be manually rotated during a setting operation in the same direct-ion in which they are driven.

Vith these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essentialelements of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany .and form part of the specification.

Of saiddrawings: Figure 1 is a left side elevation of a time printer constructed according to this invention with the casing shown in section and the clock mechanism removed. Fig. 2 is a detail of the escapement mechanism between the minute type wheel and the hour and meridian type wheels. Fig. 3 is a longitudinal vertical section of the time printer taken on the line 33 of Fig. 5. Fig. 4 is a front elevation of the time printer with part of the casingomitted. Fig. 5 is a top plan view partly in section-of the time printer. Fig.

6 is a fragmentary sectional view taken on a plane passing through shafts 8 and 73, Fig. 1. Fig. 7 is a detail of a stop device ofthe hour escapement mechanism which is shown in Fig. 6.

Described in general terms this invention comprises a clock mechanism which controls an escapement for a power dri en minute type carrier. By the rotation of the minute trolled by the minute type carrier. improved .form of setting device for the type;-

type carrier .poweris storedfor driving the hour type carrier, this power being released by an escapement mechanism which is concarriers is also provided. This setting device permits the forward rotation of the minute type carrier, the rotation of which trips the escapement mechanism of the hour type carrier so that the latter may be moved alsoin a-forward direction. These improvements have been shown applied to atype of machine illustrated in the Patents Nos.

790,045, granted May 16, 1905, and 12,360

and 12,361, reissued JuneQO, 1905, to I;

Follett, but it is to be understood that these improvements may'be'applied to other forms of time recorders.

The clock mechanism 33 as shown in Figs.

4 and 5 is of any usual construction and the' various parts thereof from the main spring to the balance wheel spring are identified by the numerals 41 to 53 inclusive. A pinion 109 secured to a shaft 34 meshes with one ofthe gears of the clock mechanism and is rotated once every two minutes. The inner end of the shaft 34 is provided with a disk 35 from which extends a pin 36. This pin 36 (see Fig. 1.) plays in the bifurcated end 37 of an arm 38 which arm is secured."

upon one end of a shaft 8. This shaft (see Fig. 3) has secured to its other end a pinion 3 which meshes with gears 4 and 5 formed upon drums 1 and 2. Inclosed within the drums 1 and 2 are motor springs, the ends of which are connected to the drums and to shafts 93 and 94. The gears 4 and5 are driven in the direction of the arrows shown thereon, by the unwinding of their springs so as to drive the shaft 8 in the direction of the arrow shown upon the pinion 3. The shaft 94 has secured to it a gear 95 which meshes with an intermediate gear 96 which in turn meshes with a gear 97 secured to the shaft 93. By turning the intermediate gear 96 in any suitable manner the 110 shafts 9 3 and 94 willberotated to wind the motor springs within the drums 1 and 2.

Instead of employing the motor drums l and 2 to drive the shaft 8 and thereby the minute type carrier as hereinafter described a single drum may be employed having a spring of sufficient strength to drive said.

. on a minute type carrier 17 to be brought into printing position because the escapement wheel 13 has only thirty teeth. A pawl 14: secured to the escapement wheel 13 engages with teeth formed upon a ratchetwheel 15 which is rigidly secured to the shaft 16 to which is also secured the minute type Wheel 17. From this construction it will be seen that as the clock mechanism drives the disk 34:, the escapement wheel 13 will be released and driven forward by the motor springs inclosed within the drums 1 and 2, the movement of the wheel 13 being imparted to the ratchet wheel 15 by the pawl 14 secured to the escapement wheel and through the shaft 16 to the minute type carrier 17. By this pawl and ratchet connection it will be seen that the minute type carrier may be advanced in a forward direction or in the same direction in which it is driven, independently of the motor spring for driving it. Suitable mechanism is provided for advancing the said type carrier independently which will be hereinafter fully described.

The shaft 16 is provided at one end with a cam 54 having a cam groove 56. A roll 57 projecting from an arm 59 plays in the groove 56 of the cam 54. A similar roll 58 projects from the arm 59 and plays upon the periphery of the cam 54. The latter roller is connected to an arm 62 similar tothe arm 59, both of these arms 59 and 62 being connected to a lever 60 which is pivoted to one of the frames 11 as at 61. The forward end of the arm 60 has attached to it one end of a spring 63, the other end of said spring being secured to a stud 64. attached to one of the frames 11 of the recording mechanism. The cam 54 makes a complete rotation once in every hour and transfers to an hour type carrier in the following manner: As a shoulder 65 of the cam 54 passes the rollers 57 and 58, the spring 63 will draw the arm 66 downwardly. The arm 60 has one end of a link 66 connected thereto as at 615, the other end of said link .being connected to a lever 68 which is pivoted upon a stub shaft 70 projecting from the frame 11. iThis lever 68 is provided at one end witha pawl79 and at the other end with a pin 80. As the arm 60 is drawn downwardly by its spring 63, the pawl 79 passes into the path of one of the teeth of an escapement wheel 76 secured to one end of a shaft 7 3, the pin 80 in the meantime being withdrawn from engagement from another of the teeth of said wheel. The pawl 79 has a limited amount of movement against the tension of the spring 81 so that the wheel 76 may be rotated one tooth by its power mechanism and then arrested as hereinafter described.

As the cam 54 connected to the minute wheel is rotated by its motive spring, the arm 60 will be rocked against the tension of its spring 63. This rocking of the arm 60 will withdraw the pawl 79 from out of engagement with one of the teeth of the escapement wheel 76, but just previous to this disengagement of the pawl 79 from the tooth of the escapement wheel 76 the pin 80 projecting from the other end of the lever 68 passes into engagement with one of the teeth of said escapement wheel and thereby arrests the same. As the arm 60 is elevated, a link 67 which connects said arm to a lever 69 rocks said lever about the stub shaft 7 6 so that the pawl 71 carried by one end of the lever will rotate a ratchet wheel 72 loosely mounted upon the shaft 73 in the direction of the arrow 74 as shown in Fig; 2. A spring 75 is located in the recess in the hub of the escapement wheel 76 (see Figs. 6 and 7), the ends 77 and 78 of said spring being secured to the ratchet wheel 72 and the hub of the escapement wheel 76 respectively. From this it will be seen that as the arm 60 is elevated by the cam 54, the lever 69 will be rocked through the link connection 67 and by means of the pawl 71 rotate the ratchet wheel 72 one step. During this rotation of the ratchet wheel, the escapement wheel 76 will be held in check by either the pawl 79 or the pin 80 carried by the lever 68 thereby tensioning the motor spring 75, connecting the wheels 72 and 76. As the shoulder 65 of the cam 54L passes the roller 57, the lever 60 will be drawn downwardly by the spring 63 thereby rocking the pin 80 out of engagement with one of the teeth of the escapement wheel 76 to allow the said wheel to move forwardly one tooth and then be arrested by the spring held pawl 79 as previously described. This shaft 73 to which the escapement wheel 76 is, secured H tion of this gear connection between the shaft 73 and the hour and meridian type carriers is thought not to be necessary as it is fully described in the previously mentioned Follett patents.

The escapements for the minute and hour type wheels are successively operated, but owing to the fact that there is a possibility of taking an impression from the type carriers just after the minute type carrier has moved from 59 to 00 and before the hour type carrier has moved to bring the succeeding hour type into printing position, the frame comprising rollers 57 and 58 and the arms 59 and 62 has a slight movement independent of the arm to which it is pivoted. By this independent movement of the pivoted frame, the type carriers are moved almost simultaneously so that the danger of taking a wrong impression therefrom is reduced to a minimum. As the minute type carrier starts to move from 59 to 00, the shoulder 65 of the cam 54 will pass beyond the center of the rollers 57 and 58 so that the tension of the spring 63 connected to the free end of the arm 60 will rock the frame carrying the rollers 57 and 58 about its pivotal point and thereby permit the rocking of the arm 00 during the movement of the minute type carrier. This rocking of the arm 60 will operate the escapement for the hour type carrier as previously described, so that the latter type carrier will move with the minute type carrier. A retaining pawl 82 secured to one of the frames 11 of the printing mechanism engages the ratchet wheel 72 and prevents retrograde movement thereof while a pawl 83 pivoted upon the stub shaft engages the teeth of the escapement wheel 76 and prevents the backward movement of said wheel. The pawl 83 is held into engagement with a tooth of the escapement wheel by a spring 84 which connects the rear end of said pawl to the arm 60.

The minute shaft 16 (see Fig. 5) has secured to it a bevel pinion 18 which meshes with a similar pinion 19 secured to the inner end of a shaft 20, the latter being supported by suitable brackets secured to the casing. Near the outer end of the shaft 20 is secured a pinion 21 which meshes with an idler 22 mounted upon a bracket 23 secured to the side frame 24. This gear 22 meshes with a pinion 24 which is provided with a hub 25 to the end of which is fastened the minute hand 26 of a time indicating mechanism. This minute hand drives the hour hand 32 through suitable intervening gearing designated by reference numerals 27 to 31 inclusive (see Fig. 1).

The minute hand could just as well be secured to the outer end of the shaft 16 and the intervening mechanism for driving the hcur hand connected thereto, thereby doing away with the bevel gearing above described if it was not desired to bring the time indicating mechanism in a position to be more conveniently read by the operator of the time recorder. The outer end of the shaft 20 (see Figs. 3 and 5) is arranged to receive a setting key 92*, as shown in dotted lines in Fig. 3, which engages with a shoulder projecting from a disk 91 secured to the shaft 20 so that the latter may be rotated to set the type carriers and the hands of the time indicating mechanism by means of the gears 18 and 19. As previously described the minute type carrier is connected with its driving mechanism so that it may be rotated in the forward direction by the setting devices independently of its driving devices and through the hour escapement mecha nism drive the hour type carrier also in the forward direction. This is considered a valuable improvement in this style of time recorder as heretofore the type carriers have been set in an opposite direction from that in which they are driven by independent setting devices. By the use of these independent setting devices, if the operator is not extremely carefulv the time indicated by the hands would be different from that on the type carriers as in setting the minute type carrier the minute and hour hands will also be set without setting the hour type carrier. Although the proper time is indicated by the hands the type carriers would not be in a position to print the corresponding. time.

The shoulder of the disk 91 secured near the outer end of the shaft 20 is provided at its rear side with an incline so that in case it is attempted to rotate the shaft in any other but the proper direction, the incline 92 would cam the key from engagement with the shoulder of the disk 91.

An inking ribbon 103 (see Fig. l) is ar ranged to pass from a spool 101 over the type carriers to a spool 102. These spools 102 are mounted upon stub shafts 98 and 99 respectively which are suitably secured by brackets projecting from the time recorder casing 100. These shafts 98 and 99 are arranged to extend through the casing 100 and are provided with knobs, not shown, by which means the ribbon 103 may be fed from one spool to the other. A platen 104 carried by a lever 105 is arranged to take an impression from type carriers upon any suitable material placed between the ribbon 103 and the platen 104. This lever 105 is pivoted at 106 to projections extending upwardly from the casing and is provided with an extension which limits the upward movement of the platen 104 by contacting with an upright 108 extending from the casing 100. The lever 105 is also provided with a clownward extension to which is secured one end of a spring 107 the other end of said spring being secured to a suitable stud projecting from the casing or the frame supporting the type carriers, This spring 107 holds the rearward extension of the platen lever 105 normally into engagement with the upright 108 and Whenever an impression is desired to be taken from the type carriers the forward end of the lever is depressed.
